Hi everyone,

I have downloaded a set of processed data of gene expression relationship, while they offered a result of q value. Since I want to use the p value to adjust the next step, how can I convert this Q value to p value?

Thanks!

Is it possible that your dataset was analyzed by a method that does not produce p-values? For example, baySeq, a tool for testing differential expression in RNA-Seq data, produces posterior probabilities from a Bayesian analysis and calculates FDR directly from them. The nature of the calculations is such that no p-value is involved.
